I'm using qt 4.4.3 with c++. I want to implement a QDomDocumentFragment object, and pass it as a return value for a function. I am using it the same way as QDomElement objects, with appendChild(): QDomDocumentFragment rootnode; QDomNode initmodnode = doc.createElement("initmod"); QDomText initmodval = doc.createTextNode("4"); initmodno...
I'm working with a group of other programmers on an open source project built using C++ and Qt. Now, we need a naming convention for widgets (and other variables generally) to use it as a standard in all of our code so that, the code gets better readability and we get better coordination between programmers. Any advice? EDIT: Am not t...

I'm just learning QT with C++. I have successfully implemented signals and slots to trap standard events like ButtonPushed(), etc. However, I want to have a function called when I mouse over and mouse out of a QLabel. It looks like QHoverEvent will do what I need, but I can't seem to find any tutorials or examples on how to implement thi...

Can someone with extensive experience with both Qt and Java Swing please discuss whether you would use Swing or Qt under Java, and why? Secondly, what is the business impact of using Qt? Is it reasonably popular or will I have a hard time finding experienced Qt developers? Are there any other business impacts I should be aware of? UPDA...
Hi! I'm writing an application that is currently a pure QT4 app. It is designed to run cleanly on both Linux and Windows. However I plan to integrate it a bit into KDE in future and here come the problems with localization/translations. QT4 uses its own tr()/tr().arg().arg() mechanism and .ts/.qm files. KDE4 uses gettext and i18n/i18n...

Most of the tutorials say to run qmake -project, then qmake and finally make. But when I try this I run into the error make: *** No targets specified and no makefile found. Stop. I dont k...
Hi, I'm inserting a hook in the MFC message loop so that the Qt events are treated, without running ->exec() on qApp (because it's blocking): LRESULT CALLBACK myHookFn(int ncode, WPARAM wparam, LPARAM lparam) { if (qApp) qApp->sendPostedEvents(); return CallNextHookEx(0, ncode, wparam, lparam); } and int argc = 0; new QAppli...
I just read a story I was hoping to read since Nokia bought Trolltech. Qt is going LGPL in March! This is awesome news. Who uses Qt for Windows? Does it effectively replace something like MFC? Sure, I can RTFM (and to some degree I have)... but what do people USING Qt on a Windows platform think of it? I still do quite a bit of M...

Everything was going well until I made some unknown change and now the widget only repaints when I move the mouse (it should be doing it all the time due to the QTimer I have firing). Relevant code: Ope...
